Developing effective drilling fluid systems for wiring holes in complicated mining and geological conditions that sustain terrigenous clay, unconsolidated sand rocks and has natural permeability is an important task. In this regard, the important role is played by physical and chemical methods for drilling unstable fluid-saturated horizons with alternating intervals of wells, which is to secure mudding walls, preventing passage of fluid from the reservoir int the wellbore. Designed gel solution influences the formation of lasting colmating screen having a high coefficient of reliability, which prevents the penetration of mud filtrate into the formation, increases the stability of the wellbore while drilling shale and limits the flow of fluid from the reservoir into the wellbore.
